Proportion of reproductive age group is higher than pre - reproductive groups in

Options

A. triangular age pyramid
B. urn- shaped pyramid
C. bell - shaped age pyramid
D. More than one option is correct

Answer

To solve the question regarding the proportion of the reproductive age group being higher than the pre-reproductive groups, we can analyze the characteristics of population pyramids.

### Step-by-Step Solution:

1. **Understand the Age Groups**:
- The reproductive age group typically includes individuals aged 15-49 years.
- The pre-reproductive age group includes children, usually aged 0-14 years.

2. **Identify Population Pyramid Types**:
- There are three main types of population pyramids: triangular, bell-shaped, and urn-shaped.

3. **Triangular Population Pyramid**:
- In a triangular pyramid, the pre-reproductive age group (children) is larger than the reproductive age group (adults). This indicates a growing population. Therefore, this type does not satisfy the condition of the reproductive age group being higher.

4. **Bell-Shaped Population Pyramid**:
- A bell-shaped pyramid indicates a stable population where the pre-reproductive and reproductive age groups are approximately equal, but it does not show a higher reproductive age group. Thus, this option is also incorrect.

5. **Urn-Shaped Population Pyramid**:
- An urn-shaped pyramid indicates a declining population. In this case, the reproductive age group is larger than the pre-reproductive group, which satisfies the condition of the question. This shape suggests that the population is declining, with fewer individuals in the post-reproductive age group.

6. **Conclusion**:
- The correct answer to the question is that the proportion of the reproductive age group is higher than the pre-reproductive age group in a population represented by an urn-shaped pyramid.

### Final Answer:
The proportion of the reproductive age group is higher than the pre-reproductive groups in an urn-shaped population pyramid.
